RESUMO
Papillary fibroelastoma (PFE) is a rare and benign cardiac tumor typically found on the valvular endocardium. In most cases, PFE is identified incidentally on echocardiography or during cardiac surgery. The patient was a 73-year-old man who had been treated for hepatocellular carcinoma for 5 years. On echocardiography, a 2.5-cm diameter mass was detected in the pulmonary trunk just above the pulmonary valve. Through a transpulmonary arterial approach with cardiopulmonary bypass, the mass identified on the commissure of the right and posterior pulmonary cusp was surgically excised together with the attached endocardium. Despite the benign histology of PFE, lethal embolic events such as stroke, myocardial infarction, and pulmonary embolism are reported in some cases. To prevent such complications, tumor identification and surgical excision are essential.
